Blogs, RSS, and Ajax

Director, Technology-Enhanced Learning, U of Illinois at Springfield
Web 2.0
• Term originated in 2004 with O’Reilly• Second generation of the Web• Collaboration, interaction, customization• Wikipedia takes on the challenge of trying to
define and explain Web 2.0• “Web 2.0 doesn't have a hard boundary, but
rather, a gravitational core”
Ajax
• Ajax = Asynchronous JavaScript and XML• Not a single technology – rather a group of
technologies working together • Truly interactive 2.0 applications• Uses
– XHTML and CSS for markup applications– JavaScript or Jscript to interact with display– XHR (xmlhttprequest) as API
Ajax
• Term first emerged about 18 months ago• Many examples are emerging:
– http://www.ajaxprojects.com/ajax/viewcategory.php?categoryid=8
– http://aln-preconference.blogspot.com • Still challenges ahead:
– ADA accessibility– Browser compatibility issues (back button)
• Many advantages in engaging the user and enabling interactivity
Blogs
• Web + Logs = Blogs• Web pages with updates in chronological (or reverse
chronological) order• 1997 term first emerged• Now 55 million blogs and growing by one a every
second!• Opportunity to enable responses from readers and
RSS dissemination make blogs 2.0 technologies
Blogs
• RSS is the key to disseminating blogs and many other Web 2.0 applications
• Many ways to capture blog feeds via RSS– http://newsisfree.com
• IE 7 and Firefox browsers along with a plethora of other services such as email programs, Yahoo, etc. support RSS aggregation
A Blog Example
• Online Learning Update– http://onlinelearningupdate.com
• Blogs enjoy high search engine ratings– Enter online learning into Google
• Blogosphere connections and popularity result in dynamic (Web 2.0) sites that include aggregations of blogs

Blog - a subject tracer information blog
Blogs for virtual conference participation
At approx. 10 health/nursing informatics events since medinfo2004
Why?
- to provide virtual interaction for those unable to attend
- to promote the event
- to play with explore the technology
- to explore/research a collaborative model of blogging
Blogs for virtual conference participation
What we hoped for:
lots of people wanting to post items
lots of comments
lots of readers
demonstration of the collaborative model working.
Blogs for virtual conference participation
What we found:
many promised but few delivered
the principal providers were the main bloggers
levels of use were lower than hoped
reminders to people help in readership levels
interaction is lower than hoped for
Blogs, interaction and participation – some evaluation data
● Generally felt to be a useful adjunct to events● Most felt was easy to use● Should be available post-event (archive)
'...personal anecdotes give a sense of voyeurism...being there without actually being physically there.'
'I like the first person 'conversation' style - as though speaking directly to me. Informal, easy to follow and relate to. If I disagreed or had comments, I knew I could add the blog to benefit other readers.'
Blogs, interaction and participation – some lessons learned
Must be as easy as possible to access and participate- eg wireless – or people won't post during the event
Reminders boost readership
RSS feeds to email/browser
Wikis
-are dynamic, group-developed web pages that can be easily created and accessed via a browser
-the content may be updated or changed by anyone visiting the website.
Wikis allow for asynchronous group socialisation, communication and collaboration and a tool for archiving documents, brainstorming, and collaborative writing.
Wikipedia (www.wikipedia.org/wiki/Main_Page), Wikinews (www.wikinews.org/wiki/Health).
Writely (now part of Google docs and spreadsheets), was 'one of the top 10 technology applications affecting education in 2005
-allows anyone to compose online and collaborate (write and edit) with others in real time.
Podcasting
• A portmanteau of “broadcasting” and “iPod”
• Audio event, conversation, lecture, song, speech, group presentation
• Delivered via RSS• Mobile device synchronized with a
computer• “Push” “Pull” technology
Podcasting
• Strengths– Instructor’s desire to assist students’ meta-
cognitive skills– Keep up with the reality of the students’ lives and
use of media– Academic podcasts easy to use: faculty and
students– Easy to access via iTunes or desktop– Students report being more engaged in lecture
Podcasting
• Concerns– Slackers will skip class!– Visual images not captured as in F2F
• Remedy may be podcasts with video
• Future?– Empirical research needed– N340 Principles and Methods Fall 06– An increase in number of faculty using MP3
technology in the classroom
